[Think Tank] Cache DNS Requests on Android to speedup browsing
I was wondering if there is a method to cache DNS requests? I use CM latest and was browsing around in the system folder, when i came by /system/etc/resolv.conf. Here you find the nameservers used by android to resolve DNS.
This got me thinking, because I use a DNS cache on my Ubuntu Box. Might there be a way to do this on Android, to speed up browsing regularly visited websites? Does anyone have any idea how to use a local DNS cache to speed up browsing?
Here's the deal:
- In /system/etc/resolv.conf you find 4 nameservers (126.96.36.199 - 188.8.131.52)
- Doing a ping test (count = 1000) to those, i find big differences in latency. Average was 800 on my test on 3G (I live in the Netherlands). I found this number rather large.
- On IRC, when asking this question, they mentioned porting dnsmasq to android and change nameserver to localhost
A ported version of dnsmasq is found here: http://code.google.com/p/android-wif...c=svn120&r=120
Copied the file to /system/bin, chmod +x the file, and this one works.
Now here's the thing:
- dnsmasq --help mentions a configurationfile: /data/local/dnsmasq.conf. This one have to be made for android
- how to configure dnsmasq so it uses the DNS servers and create a cache, thus speeding up browsing (in my humble belief)
- how to start dnsmasq on booting android (and making sure it stays alive)
And finally, does it make sense to use this kind of method? Like to apply for a think tank to make this work
